Supercritical interaction is the condition when there is a definite flow separation and recirculation zone in front of the protrusion. In the former, the maximum heat flux point is expected to be to the sides of the protrusion, whereas...

We performed a parametric study and found that the large-scale vortices travelling along the channel walls between the neighboring baffles, which are generated by flow separation at the tips of the baffles and become unsteady due to a Hopf bifurcation from steady...
